Think of the difference between a typewriter and a computer. They’re two different technologies that can be used to write a book. But it makes not sense to ask, “Are books written on computers good or bad?”

Using genetic modification let’s us “copy and paste” a specific gene that makes it better.

How does this work in corn? To make Bt corn, researchers flipped one gene from a naturally occurring soil bacteria and pasted it in traditional corn to make caterpillars stop eating it. Simple. We get a corn that is unchanged and we get a better corn.
